- Programmable current source The TP1001S3 is a high side current sense monitor. Using this device eli minates the n eed to disrupt the ground plane when sensing a load current. It takes a hig h side voltage developed across a current shunt resistor and translates it into a proportional output current. A user defined output resistor scales the output current into a ground-referenced voltage. The wide input voltage range of 20V down to as low as 2.5V make it suitable for a range of applications. A minimum operating current of just 4µA, combined with a SOT23 package make it a unique solution for portable battery equipment. HIGH-SIDE CURRE NT MONITOR All d ata sheet.com
